Mandevilla plant named ‘Sunparausupi’

ABSTRACT

A new and distinct cultivar of  Mandevilla  plant named ‘Sunparausupi’, characterized by its compact and vining plant habit; vigorous growth habit; freely branching habit, dense and bushy plant form; dark green-colored leaves; freely flowering habit; long flowering period; and medium-sized pink-colored flowers.

Botanical designation: Mandevilla hybrida.

Cultivar denomination: ‘SUNPARAUSUPI’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Mandevilla plant, botanically known as Mandevilla hybrida and hereinafter referred to by the name ‘Sunparausupi’.

The new Mandevilla plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new compact, freely-branching and vining Mandevilla plants with numerous medium-sized attractive flowers.

The new Mandevilla plant originated from a cross-pollination in Higashiomi, Shiga, Japan in April, 2006 of a proprietary selection of Mandevilla hybrida identified as code number 02M11-1, not patented, as the female, or seed parent with a proprietary selection of Mandevilla hybrida identified as code number MH-5, not patented, as the male, or pollen, parent. The new Mandevilla plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in October, 2007.

Asexual reproduction of the new Mandevilla plant by cuttings in Higashiomi, Shiga, Japan since October, 2007 has shown that the unique features of this new Mandevilla plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Mandevilla have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunparausupi’. These characteristics in combination distinguish ‘Sunparausupi’ as a new and distinct Mandevilla plant:

-   -   1. Compact and vining plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit, dense and bushy plant form.     -   4. Dark green-colored leaves.     -   5. Freely flowering habit.     -   6. Long flowering period.     -   7. Medium-sized pink-colored flowers.

Plants of the new Mandevilla can be compared to plants of the female parent selection. Plants of the new Mandevilla differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Mandevilla are more compact than plants of         the female parent selection.     -   2. Plants of the new Mandevilla have shorter lateral branches         with shorter internodes than plants of the female parent         selection.     -   3. Plants of the new Mandevilla and the female parent selection         differ in flower color as plants of the female parent selection         have dark red-colored flowers.

Plants of the new Mandevilla can be compared to plants of the male parent selection. Plants of the new Mandevilla differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Mandevilla are not as compact as plants of         the male parent selection.     -   2. Plants of the new Mandevilla have longer lateral branches         with longer internodes than plants of the male parent selection.     -   3. Plants of the new Mandevilla and the male parent selection         differ in flower color as plants of the male parent selection         have pale pink-colored flowers.

Plants of the new Mandevilla can be compared to plants of the Mandevilla ‘Sunpararosta’, disclosed in U.S. Plant Pat. No. 23,213. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Mandevilla differed from plants of ‘Sunpararosta’ in the following characteristics:

-   -   1. Plants of the new Mandevilla were more compact than plants of         ‘Sunpararosta’.     -   2. Plant of the new Mandevilla had shorter lateral branches with         shorter internodes than plants of ‘Sunpararosta’.     -   3. Flowers of plants of the new Mandevilla had ovate-shaped         petals whereas flowers of plants of ‘Sunpararosta’ had         orbicular-shaped petals.     -   4. Flowers of plants of the new Mandevilla were lighter pink in         color than flowers of plants of ‘Sunpararosta’.     -   5. Plants of the new Mandevilla had shorter peduncles and         pedicels than plants of ‘Sunpararosta’.
